Droopy is the name of a cartoon dog created in 1943 by Tex Avery and featured in a number of animated short movies produced by the Metro-Goldwyn-Mayer cartoon studio. Originally he did not have a name and was then called Happy Hound before being named Droopy in 1949.

Droopy's meek, deadpan voice and personality were modeled after the character Wallace Wimple on the radio comedy Fibber McGee and Molly; actor Bill Thompson, who played Wimple, was the original voice of Droopy.
